Feeding device for automotive door panels

The present invention relates to a door panel transfer device used in an assembly plant of an automobile, and more particularly, to a door panel transfer device for automatically transferring a door panel to another process, and a shock absorber To a transfer device for a door panel of an automobile.

Generally, in automobile assembly lines, various transport devices are used as part of automation. For example, door frames or follower panels are usually transported from one workplace to another by using a transfer device.

As shown in FIG. 2, the conveying conveyor includes a conveying conveyor for conveying the door panel 11 in a stable manner so as to advance in order A plurality of panel supports 12 installed at predetermined intervals and a plurality of roller support members 12 integrally formed under the plurality of panel support members 12 to advance the panel support members 12 by the operation of an electric drive motor And a base frame 14 provided at the upper and lower ends so as to guide the progress of the roller 13 and to support the panel support 12 and the roller 13 from the bottom have.

When the panel support table 12 and the roller 13, on which the door panel 11 is mounted on the upper base frame 14a, are moved forward by a predetermined distance in the base frame 14 installed at the two ends, The panel support 12 and the roller 13 from which the door panel 11 is taken out are rotated in the downward direction so that the lower portion of the door panel 11 is rotated in the downward direction, The upper and lower base frames 14a and 14b are continuously rotated by returning to the base frame 14b so that the door panel 11 can be automatically transferred.

The door panel 11 is tilted forward to stop the door panel 11 on the stopper 15 immediately before the hanger for lowering the door panel 11 is lowered, So that the door panel 11 can be easily transferred to the hanger.

When the door panel 11 is tilted to the stopper 15 in order to enlarge the space between the door panels 11 at the final stage of the operation of the door panel transfer device, There is a problem that the workability is lowered and the quality is deteriorated.

Accordingly, it is an object of the present invention to solve the above-mentioned problems, and it is an object of the present invention to provide an automatic door opening and closing device for a door panel, And an object of the present invention is to provide a transfer device for a door panel for an automobile which can prevent the door panel from being damaged.

According to an aspect of the present invention, there is provided a door panel comprising: a plurality of panel supports which are installed at predetermined intervals so that the door panels can be stably placed and advanced in order; A base frame provided at the upper and lower ends so as to guide the progress of the roller and to support the panel support and the roller from the lower side, And a stopper adapted to fix a door panel for an automobile having a stopper for fixing the door panel, the door panel comprising: So that the operating cylinder provided with a rotating bar at the tip end of the stopper A structure, characterized in that provided in the connection portion.

A cushion cylinder having a cushioning member attached to the stroke end of the door panel is installed at the upper portion of the stopper so as to be able to seat the door panel at a predetermined distance from the detector. Is installed.

Accordingly, since the door panel can be automatically taken out and transferred to another process by the door panel transfer device having the above-described structure, the working efficiency is improved and the quality is improved. Further, when the door panel is taken out, It is possible to prevent damage to the door panel.

DESCRIPTION OF THE REFERENCE NUMERALS

1: Door panel 2: Panel support

3: roller 4: base frame

5: Stopper 6: Operation sensor

7: Rotating bar 7a: Buffer member

8: Working cylinder 9: Detector

10: Buffer cylinder 10a: Stroke

10b: buffer member

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings.

FIG. 1b is a perspective view of the operation sensor of FIG. 1a, FIG. 1c is a perspective view of the door panel transfer device installed in the door panel transfer device to automatically lock the door panel. FIG. 1b is a perspective view schematically showing the door panel transfer device according to the present invention. And Fig. 3 is a perspective view schematically showing a shock absorbing cylinder installed in a stopper of the first d or door panel transfer device.

As shown in the drawings, the door panel transfer device according to the present invention includes a plurality of panel support rods 2 integrally formed at a lower portion of the panel support rods 2 at regular intervals so that the door panel 1 can be stably placed, The panel 3 supports the panel support 2 by the operation of an electric drive motor (not shown), guides the roller 3 and guides the roller 3 of the panel support 2 And the door panel 1 is attached to the operation sensor 6 at one side of the stopper 5 in a direction perpendicular to the front end of the base frame 4, And an operating cylinder 8 provided with a pivoting bar 7 is connected at the tip thereof to be automatically tilted.

A sensor 9 for sending a signal to a transfer hanger (not shown) in contact with the door panel 1 is installed on the upper portion of the stopper 5 and a door panel 1, a cushion cylinder 10 having a cushioning member 10b attached to the tip of the stroke 10a is provided.

That is, when the door panel 1 is inserted into the panel support 2 of the transfer device to transfer the door panel 1 after the hemming process to another process, the roller 3 is moved by the operation of the electric drive motor When the panel support 2 advances and the door panel 1 advancing on the upper base frame 4 arrives at the exit of the conveying device, the operation sensor 6 at the entrance side sends a signal to the exit door The cylinder 8 rotates the pivoting bar 7 to push the door panel 1 to the stopper 5 and fix it.

The door panel 1 is fixed to the stopper 5 and the detector 9 is brought into contact with the door panel 1 to operate the transfer hanger so as to prepare the door panel 1 for transfer The door panel 1 is elastically supported on the cushioning member 10b at the front end of the stroke 10a by the operation of the shock absorber cylinder 10 in which the door panel 1 is seated and fixed, It is possible to do.

Cushioning members 7a and 10b are attached to the pivotal bar 7 of the actuating cylinder 8 and the stroke 10a of the shock absorbing cylinder 10 to protect the inner and outer plates of the door panel 1 And the stroke 10a of the shock absorbing cylinder 10 smoothly fixes the door panel 1 while absorbing the impact of the door panel 1 which is pushed by the pivoting bar 7 of the actuating cylinder 8 I will give you.

As described above, according to the present invention, since the door panel can be automatically taken out and transferred to another process, the work efficiency is improved and the quality is improved. In addition, when the door panel is fixed A buffer cylinder is installed to prevent damage to the door panel.
